RAILROAD-RAIL-FASTENING DEVICE.

Specification of Letters Patent.

Patented Aug. 2, 1910.

Application filed November 12,1909; Serial No. 527,670.

To all whom 'it may. concern:

Be it known: that 1, Louis DORVILLE CHABUT, a citizen of the United States, residing at Youngstown, in the county of Mahoning, State of Ohio, have invented certain new and useful Improvements in Railroad-Rail-FasteningDevices; and I do hereby declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the Same.

This invention relates to improvements in railway rail fastening devices and has for its object the provision of a device of that kind, whereby the rail may be secured. to the tie without the use of spikes.

- Another object is the provision of a rail provided with a plug and a tie provided with a socket to receive the plug and a locking pin passing through the tie ,and plug, whereby the rail is locked tothe tie. I

A further object is the provision of a means for sealing the opening through which the locking pin passes in order to prevent accidental displacement of the locking Withthese and other objects in view as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustratedin the accompanying drawings and more particularly pointed out in the appended claims; it being understood that various changes in the form, proportion, size and.

minor details of the device may be made without departing from the spirit or. sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of the specification'z-Figure 1 is a portion of a rail in longitudinal section and showing my improved device positioned to secure the rail to the tie. Fig. 2 is a transverse section of a rail and longitudinalsection of a portion of a tie and showing the device in side elevation. Fig. 3'is a side elevation of the lug. Fig. 4 is a perspective view of the closure cap for the locking pin.

Similar numerals of reference are employed to designate corresponding parts throughout.

The'tread of the rail is designated by the numeral 5, the base flange by the numeral 6,.

and the web uniting the base flange with the tread by the numeral 7. These parts are all tailed description of the sameneed not be given.

The cross tie forming a portion of the subject-matter of the present invention is designated in general by the numeral 8, and may be of wood, metal or other suitable material. Formed in the upper face of the tie and, adjacent either end thereof is a noncylindrical-socket 9, whichextends approximately half way through the tie and extendin inwardly from either end'of the tie is an axial bore 10, the inner end of which communicates with the socket 9. The outer end portion of the bore 10 is counterbored as shown at 11, and interiorly screw threaded; {he function of this construction-Will appear ater. I

The plug for uniting the rail with the tie is designated by the numeral 12, and is shown to be formed of a cube of steel, of a size to nicely fit within the socket 9. When the plug is positioned in the socket as shown' in Figs. 1 and 2 its upper side will be flush with the upper face of the tie 8, and arranged onthe u per face of the plug is-an exteriorly threa ed boss 13'. The boss 13 is circular 1n contour and of considerably lesslength and width than the plug.

By reference now to Figs. 1 ,and2, it will be seen that formed in the central portion of the lower flange 6 of the rail is a threaded opening 14, of a depth and diameter to receive the boss 13. It is to be understood that the base flan e of the rail is provided with a pluralit o spaced apart fhr'a distance corresponding to the space between the longitudinal centers of the cross ties so that when the rails are positioned on the cross ties they are secured to the latter in a manner to be presently described.

By reference now to Figs. 1 and 2,it will be seen that the plug 12 is medially provided with a transverse aperture 15, adapted to these openings which areaxes of the apertures 15 are perpendicular to the longitudinal center of the rail. When the parts are so positioned the rail is placed upon the cross ties and the plugs inserted into the sockets after which the locking pins are passed through the bores, whereby the parts are held against displacement.

It will be observed b reference to Fig. 2 that the head of the loc ing pin 16 is seated in the counterbore l1 and in order to prevent accidental displacement of the locking pin, due to the jarring produced by passing trains and at the same time to positively prevent tampering, a threaded cap 17 is provided.- This member is provided with a fiat outer surface having a pair of oppositely arranged depressions to receive a suitable tool by means of which the cap may be threaded into the counterbore l1 and bear on the head of the locking pin. The cap is of such thickness that when ithas been com pletely threaded into the counterbore, its outer surface is substantially flush with the end of the tie and owing to the absence of projections on the said outer surface it will be impossible to remove the cap without-the aid of a suitable tool. Thus it can be seen when the parts are positioned as shown in Fi s. 1 and 2, that the rail will be securely locked to the tie and danger of its displacement reduced to a minimum.

IV hat is claimed as new, is

1. In a rail fastening device, a rail provided on its base flange with an apertured plug, a tie provided with a socket to receive the plug and further provided with an axial bore in alinement with the aperture of the plug and a locking pin passing into the bore of the tie and aperture of the plug.

2. In a rail fastening device, a rail provided on its base flange with an opening, a non-cylindrical apertured plug having a boss at one end threadable into said opening, a cross tie provided with a socket to receive said plug and further provided with an axial bore communicating with said plug and a locking pin passing into the bore of the tie and aperture of the plug.

3. In a rail fastening device, a rail pr0- vided on its base flange with a depending apertured plug, a tie provided with a socket to receive said plug and further provided with a bore the inner end of which ter- Ininates in said socket and the outer end of which is enlarged and interiorly screw threaded, a locking pin passing into said bore and through the apertured plug and a cap threadable into the enlarged portion of the bore and bearing on the outer end of the locking pin.

In testimony whereof, I aflix my signature, in presence of two witnesses.
